Migration, Remittances, And Child Growth: Evidence From Cambodia, Vatana Chea, Patcharawalai Wongboonsin

Journal of Demography

Remittances have become a main resource for development in low- and middle-income countries around the world. With impressive growth in remittances over the decades comes interest in their importance to development. Using data from the 2009 Cambodian Socio-Economic Survey with a sample of 2,767 children under 5 years of age, this study investigates the impact of migration and of remittances on children's quality of health, and tests whether or not the so-called permanent income hypothesis holds for remittances relative to other income. Also employed is two-stage least squares analysis to account for potential endogeneity problems. In short, it was found …

The Presence Of Orthorexic Eating Behaviors In Students Studying Health Sciences, Sophia Weiner

West Chester University Graduate Theses, Dissertations, and Final Projects

Orthorexia nervosa is a novel type of disordered eating characterized by a hyper fixation on the consumption of clean, healthy, and morally pure foods as delineated by the individual (Dunn & Bratman, 2016). Previous studies have suggested that individuals studying physical health-related subjects such as nutrition and exercise science endorse more orthorexia nervosa symptoms than those in non-physical health-related areas (Malmborg et al., 2017; Plichta & Jezewska-Zychowicz, 2019). The present study sought to explore the relationship between college major, gender, and levels of body appreciation in the frequency of orthorexia nervosa symptomatology. It also aimed to assess orthorexia nervosa's relationship …

Turning To The Sacred: The Role Of Religious/Spiritual Coping In Psychological Outcomes Of Childhood Interpersonal Trauma, Vanessa S. Tomasik

College of Graduate Studies: Theses & Dissertations

Adverse Childhood Experiences (ACEs) are widespread and associated with significant and lasting psychological consequences, including posttraumatic stress symptoms (PTSS) and dissociation. Much of the existing literature has focused on adult trauma or narrowly examined childhood abuse and neglect, with comparatively limited attention given to other forms of childhood adversity such as witnessing intimate partner violence, parental separation, or household dysfunction. As a result, the differential psychological impact of distinct types of ACE exposure (i.e., maltreatment vs. household dysfunction) remains insufficiently understood. Emerging literature on coping identifies religious and spiritual (R/S) coping as an important factor in trauma adaptation. Positive R/S …

Sexual Di(Et)Morphism: Using Experimental Evolution To Test Whether Resource Partitioning Promotes Divergence Of The Sexes In Drosophila Melanogaster, Owen A. Jamieson

Theses and Dissertations (Comprehensive)

Sexual dimorphism has been a long-studied phenomenon in the field of evolutionary biology. Usually, these differences in morphology, physiology and/or behaviour between the sexes are studied through the parsimonious lens of sexual selection. However, there are natural history cases where this lens does not seem applicable. Some species show sex specific morphological traits whose presence may not be due to a direct benefit to reproduction, but a difference in how each sex interacts with the environment and differing selective pressures from the environment on either sex. Darwin even brought up examples of this kind of dimorphism and pondered their existence, …

When Probiotics Guidelines Differ: A Practical Guide For Clinicians And Researchers, Geoffrey A Preidis, Hania Szajewska, Marla Cunningham, Howard Bauchner, Daniel J Merenstein

Faculty, Staff and Students Publications

Many professional organizations publish clinical practice guidelines for the use of probiotics in gastrointestinal disorders. Generally, no two guidelines align perfectly, and some differ markedly. These discrepancies occur because clinical practice guidelines are not purely mechanical outputs of data synthesis. They are shaped by structured interpretation, value judgments, and predefined thresholds for uncertainty. These elements become particularly visible when effect sizes are small, heterogeneity is high, and outcomes vary in clinical relevance-as is the case with probiotic research. This article examines why discordance among probiotic guidelines is predictable and provides practical guidance for clinicians who must decide among conflicting recommendations …

School of Public Health Faculty Publications

Background: Dietary management is key to preventing and controlling type 2 diabetes mellitus (T2DM). However, few studies have examined differences in Healthy Eating Index (HEI-2020) scores and components among individuals with and without diagnosed T2DM. This study aimed to assess gender differences in HEI-2020 scores and its 13 components by T2DM status. Methods: Using National Health and Nutrition Examination Survey (NHANES) data from 2011 to 2018, this cross-sectional study analyzed 19,464 adults. Diagnosed T2DM was identified via self-report or diabetes medication use. Diet quality was assessed using the HEI-2020, scored from 0 to 100, with a higher HEI score indicates …

Nourishing Births: A Program Evaluation Proposal For Community-Based Nutrition Education, Food Access, And Garden Engagement Among Black Birthing People, Naa Deedei-Vera Hammond

Master's Projects and Capstones

Black birthing people in the United States continue to experience unequal maternal health outcomes, shaped in part by racism and barriers to nutritious food, culturally relevant health education, and supportive community spaces. While prenatal nutrition education and food assistance programs can provide important resources, information alone cannot address the challenges many people face when trying to access healthy and affordable food during pregnancy. The Nourishing Births Initiative is a proposed community-based maternal health program designed to respond to these needs by bringing together prenatal nutrition education, help connecting to food resources, community gardening, and peer support for Black birthing people …

Knowledge, Attitudes, And Practices (Kap) Of Parents Regarding The Prevention And Control Of Childhood Iron Deficiency Anemia In Egypt: A Cross-Sectional Study, Omnia Soliman

Theses and Dissertations

Childhood Iron Deficiency Anemia (IDA) remains a major public health challenge in Egypt, where its persistently high and rising prevalence carries substantial consequences for child growth, cognitive development, immunity, and long-term health outcomes. Globally, approximately 40% of children aged 6–59 months are affected by anemia (World Health Organization, 2025), and Egypt mirrors this burden, with national data showing a worsening trend in recent years. In Egypt, national strategies have traditionally focused on biomedical interventions such as iron supplementation and food fortification, while less attention has been directed toward behavioral and household-level determinants, particularly parental knowledge, attitudes, and practices (KAP) related …

Analysis Of U.S. Army Body Composition Policies: Implementation Effectiveness And Recommendations For Policy Enhancement At Brooke Army Medical Center, Michael L. Rizzo

Doctor of Nursing Practice (DNP) Manuscripts

US Army body composition policies (AR 600-9 and recent directives) are essential for military readiness, injury prevention, and force health protection, yet implementation gaps persist, particularly with the 2026 Department of Defense (DoD)-mandated waist-to-height ratio (WHtR < 0.55) transition. This DNP project evaluated policy implementation effectiveness at Brooke Army Medical Center using the W.K. Kellogg Foundation Logic Model and CFIR 2.0 framework. Analysis of 2022–2025 de-identified administrative data and 16 stakeholder questionnaires identified ≥10 implementation gaps, including low awareness of new standards and workload impacts. The project developed 8 evidence-based recommendations and an implementation roadmap to improve compliance, optimize resources, reduce administrative burden, and strengthen military readiness.

Implementing Updated Npo Guidelines For Inpatient Procedures, Yasamin Ghanivand

Doctor of Nursing Practice (DNP) Projects

Background: Nil per os (NPO) guidelines are utilized for patient safety during procedures to reduce the risk of pulmonary aspiration. The American Society of Anesthesiologists (ASA) recommends clear liquids up to 2 hours before non-emergent procedures, although many facilities still implement the outdated practice of ordering NPO after midnight. This practice can lead to prolonged fasting, which may cause increased hunger, thirst, hypotension, nausea, and dizziness, ultimately resulting in patient dissatisfaction and discomfort.

Purpose: To review and assess current ASA NPO guidelines that describe best practice to enhance the patient experience without increasing perioperative risk of pulmonary aspiration.

Methods: A …

Balancing Root-Zone Oxygenation And Rhizosphere Stability: The Impact Of Aeration And Hypoxia On Hydroponic Plant Growth, Christian D. Baker

All Graduate Theses and Dissertations, Fall 2023 to Present

As the global population and food demand continue to increase, growers must look to innovative and sustainable methods for plant cultivation. Hydroponics is a popular method of sustainable plant cultivation where plant roots are suspended over a liquid nutrient solution. Hydroponics uses less water compared to traditional agriculture because there is no evaporation or solution runoff. It also maximizes land use, requires fewer pesticides and herbicides, and enables year-round cultivation in controlled environments. However, indoor hydroponic systems rely on artificial lighting, which has higher energy costs than traditional farming methods. Optimizing growing conditions is therefore critical to ensure long-term economic …

Toward Optimizing Fruit Production In Utah Soils: Apple Salt Tolerance Screening And Tart Cherry Fertility Management, Kaitlin Dabbs

All Graduate Theses and Dissertations, Fall 2023 to Present

Fruit production in Utah can be challenging due to local climate and soil conditions. Tart cherries and apples are major fruit crops in Utah, and improvements to these cropping systems would be beneficial for farmers and local consumers. Two experiments were conducted to evaluate desired improvements for these crops. The first study looked for salt tolerance in ten new apple rootstocks. Salty soils can be found throughout the state limiting the land suitable for apple production. When grown in salty soils apple trees often have reduced growth and production potential. A specialized drip irrigation system was constructed in a greenhouse …

The Relationship Between Dietary Sodium Intake And Cognitive Function: A Narrative Review, Samantha L. Gardener, M. Fu, L. Morini, T. Schwartzkopff, G. Savage, R. N. Martins, S. R. Rainey-Smith

Research outputs 2022 to 2026

Purpose of Review: This narrative review provides discussion on current evidence regarding the relationship between sodium intake and cognitive function in animal and human studies, as well as potential mechanisms underlying this relationship. Recent Findings: Recent evidence suggests high sodium intake is associated with development of cognitive impairment and neural dysfunction. Additionally, studies have proposed that high sodium intake is associated with increased aggregation of Aβ-amyloid and that hypertension (for which high sodium intake is a risk factor) modulates the relationship between Aβ-amyloid and development of cognitive impairment and Alzheimer’s disease. However, while animal studies demonstrate a consistent relationship between …

Bone, Muscle, And Physical Function Measures In Older Adults According To Levels Of Social Disadvantage: A Cross-Sectional Study, Jason Talevski, Sharon Brennan-Olsen, Stefanie Bird, Sara Vogrin, Alison Beauchamp, Mizhgan Fatima, Cassandra Smith, Gustavo Duque

Research outputs 2022 to 2026

Summary: This cross-sectional study of 300 older adults (aged ≥ 50 years) found that less education, lower income, and health care card ownership are associated with reduced bone, muscle, and physical function measures. This underscores the need for targeted preventive strategies for osteoporosis and sarcopenia that address socioeconomic-related disparities. Purpose: The prevalence of chronic diseases follows a social gradient, although this is unclear in musculoskeletal conditions. This study aims to examine the association between social disadvantage and diagnostic measures of osteoporosis and sarcopenia in community-dwelling older adults. Methods: A single-centre, cross-sectional study was conducted in adults (≥ 50 years) residing …

Local Government Policies Restricting Unhealthy Outdoor Food Advertising In Australia: Stakeholder Perspectives Identify Political Willingness Is Key To Overcoming Barriers, Alexia Bivoltsis, Frith Klug, Jacinta Francis, Clare Whitton, Gina S.A. Trapp, Claire E. Pulker

Research outputs 2022 to 2026

Background: Unhealthy outdoor food advertising is strongly linked to poor diet, highlighting the need for policies. Western Australian (WA) local governments (LGs) can restrict advertising on their owned infrastructure through their Public Health Plans, but limited policy action has occurred. This study aimed to explore the perspectives of WA LGs and public health organizations (PHOs) on current and potential policies restricting unhealthy outdoor food advertising on LG owned infrastructure to (1) identify barriers and enablers to the policy making process, (2) assess the current level of political willingness (i.e. political want, political can and political must) and (3) inform development …

Utilizing The Invasive Fruitwood Pyrus Calleryana As Substrate For Mushroom Cultivation, An Experimental Study In Practical Sustainability, Matthew D. Helton

Masters Theses and Doctoral Dissertations

This study evaluated the feasibility of using woodchips from the invasive Pyrus calleryana (Callery pear) as substrate for mushroom cultivation. Pleurotus ostreatus, Hericium erinaceus, and Ganoderma lucidum were grown on a pear wood substrate and on a conventional oak substrate to compare, yield, sensory attributes, and metabolite production. P. ostreatus showed no significant differences in yield or biological efficiency (p > 0.05), only sweetness (p = 0.022) differed significantly. H. erinaceus yield and efficiency were similar (p > 0.05), with greater second-flush yields in oak controls (p = 0.034) but no sensory differences (p > 0.05). G. lucidum performance was comparable across treatments …

Weathering The Divide: Social Determinants, Neighborhood Context, And Systemic Lupus Erythematosus Among African American Women, Vanessa Cl Morman

Electronic Theses and Dissertations

Background: Systemic lupus erythematosus (SLE) disproportionately affects African American women and contributes to racial health disparities in the United States. Although genetic susceptibility influences disease risk, growing evidence suggests that social determinants of health (SDOH), including neighborhood conditions, structural racism, and socioeconomic disadvantage, contribute to disease development and progression. Epigenetic mechanisms may provide a biological pathway linking adverse social conditions to chronic disease disparities. This dissertation examined the influence of SDOH on SLE disparities through evidence synthesis and empirical investigation to inform public health practice and policy.

Methods: This integrated learning experience consisted of three complementary manuscripts. Aim 1 was …

Leveraging Mammal Mycophagy To Determine Environmental Drivers Of Truffle Diversity, Brittany Hartsock

Electronic Theses and Dissertations

Many mycorrhizal fungi are hypogeous (truffle-forming), producing underground fruiting bodies. Studying truffles is inherently challenging due to their hidden nature. However, mycophagous mammals provide a unique opportunity to study hypogeous fungi because they rely on truffles as a food source. Although several truffle species have recently been described in the southern Appalachian region, their fruiting patterns remain poorly understood. To address this, we quantified truffle richness and spore loads from 670 Peromyscus scat samples collected across 42 sites spanning an environmental gradient during 2024 in the Blue Ridge Mountains of East Tennessee. We found that truffle richness and spore abundance …

Research outputs 2022 to 2026

The external school food environment, comprising food outlets and marketing near schools, shapes what young people eat. Yet little is known about how Australian adolescents perceive and navigate these environments. Focus groups were conducted with 31 school students (Years 7–12) from Perth, Western Australia, to explore their experiences of the external school food environment and its influence on their food-related behaviours. Transcripts were thematically analysed and six themes were identified. Accessibility emphasised proximity, transport links, opening hours and speed of service, with older students using outlets as social spaces. Availability of slushies, energy drinks, snacks and fast-food meal deals influenced …

Temptation At The School Fence: A Qualitative Exploration Of The Impact Of External Food Outlets On The School Community, Sharonna Mossenson, Klug, Jacinta Francis, Siobhan Hickling, Lukar Thornton, Gina Trapp

Research outputs 2022 to 2026

Retail food outlets are commonly located in close proximity to schools, providing students with opportunities to purchase and consume food enroute to or from school. These outlets are typically unhealthy and disproportionately clustered near schools, and this trend has been increasing over time. While quantitative studies have established associations between school food environments and adolescent dietary behaviours, little is known about how school personnel perceive and experience their impacts. This qualitative study explored perspectives of school personnel (n = 9) from a secondary school in Perth, Western Australia, located 150 m from two retail food precincts (areas with a high …

Body Mass Index, Prebiotic Supplementation During Pregnancy And Gestational Diabetes Mellitus Risk: An Effect Modification Analysis From A Randomised Controlled Trial, Rachelle A. Pretorius, Thomas R. Sullivan, Summer V.M. Walker, Johan Garssen, Jeffrey A. Keelan, Desiree Silva, Susan L. Prescott, Debra J. Palmer

Research outputs 2022 to 2026

Background: Prebiotic dietary supplementation has been shown to improve glucose homeostasis in type 2 diabetes patients. The aim of this analysis was to determine whether pre-pregnancy body mass index (BMI) modifies the effect of prebiotic supplementation from mid-pregnancy on reducing the risk of gestational diabetes mellitus (GDM). Methods: In a double-blinded, randomised controlled trial, pregnant women < 21 gestational weeks were randomly assigned (1:1) to consume daily prebiotics (14.2 g galacto-oligosaccharides and fructo-oligosaccharides) or placebo (8.7 g maltodextrin) powder. An effect modification analysis was performed to assess the heterogeneity of the effect of prebiotic supplementation in relation to pre-pregnancy BMI on GDM diagnosis. Results: Between June 2016 and November 2021, 329 women were assigned to the prebiotic group (50.4%), and 323 (49.5%) were assigned to the placebo group. Overall, 288 of 652 women (44.2%) were classified as overweight/obese prior to pregnancy (BMI ≥ 25 kg/m²). The distribution was balanced, with 146/329 (44.4%) randomised to the prebiotics group and 142/323 (44.0%) in the placebo group. Pre-pregnancy BMI modified the effect of prebiotic supplementation, with the intervention reducing GDM rates in women with a BMI ≥ 25 kg/m^{2 …}
